5-Axis CNC Machining

5-axis CNC machining lets us cut complex, free-form and deep-cavity parts in fewer setups — impellers, turbine blades, manifolds, medical implants and aerospace brackets. By tilting the tool against the part, we use shorter, stiffer tools for better surface finish and tighter tolerances, while cutting multi-side features in one clamping.

Why 5-Axis Matters for Your Part

  • Fewer setups — all five sides machined in one clamping, eliminating stack-up error between operations.
  • Better surface finish — shorter toolholder reaches reduce chatter, ideal for impellers and blades.
  • Complex geometry — undercuts, angled holes, twisted pockets and sculpted surfaces in one program.
  • Lower cost — less fixturing, less labor, faster lead time for complex parts.

200+

In-House Capacity

200+ CNC mills, lathes and 5-axis machines under one roof. No subcontracting — we control quality and lead time.

60+

Countries Served

Door-to-door DHL/FedEx or sea freight. Full tracking, customs handled, FBA-ready packaging on request.

NDA

Your Drawings Are Safe

Standard NDA before quoting. Files stored on encrypted internal servers, never shared or reused.

QUALITY CONTROL SYSTEM

Precision Inspection In Every Production Stage

CMM 3D precision inspection

01 CMM 3D Precision Inspection

Verify critical dimensions, hole positions and complex GD&T geometric tolerances via professional CMM equipment. Full 3D scanning avoids assembly defects for complex machined components.

In-process dimensional verification

02 In-process Dimensional Verification

Continuous in-process dimensional testing with precision measuring tools. Early defect identification minimizes scrap risk during mass OEM production.

Surface finish and visual inspection

03 Surface Finish & Visual Inspection

Strict inspection on surface finish, scratches, burrs and coating defects. Meet strict appearance requirements of aluminum alloy housings.

First Article Inspection

04 First Article Inspection (FAI)

Standardized first article inspection before mass production. Deliver formal FAI reports to stabilize dimensional consistency for bulk orders.

Raw material traceability

05 Raw Material Traceability Management

Complete material certification & batch records. All machined parts can trace back to raw material source for IATF 16949 automotive compliance.

Final functional performance check

06 Final Functional Performance Checks

Comprehensive final functional inspections to identify hidden defects that dimension testing cannot catch, guarantee stable part performance.

Salt spray corrosion test on CNC machined parts

07 Salt Spray Corrosion Test

Neutral salt spray chamber evaluates anti-corrosion performance of anodized, plated and coated CNC parts, verifying long-term outdoor and humid-environment durability to ASTM B117 standards.

Aging and pressure durability test equipment

08 Aging & Pressure Durability Test

Simulate real-world working conditions — temperature cycling, vibration and repeated load — to verify long-term mechanical reliability and prevent premature field failure of precision machined components.
